英文摘要 | the conversion of n-c4h10 was undertaken on moo3/hzsm-5 catalyst at 773-973k and the phases of molybdenum species were detected by xrd. the xrd results show that bulk moo3 on hzsm-5 can be readily reduced by n-c4h10 to moo2 at 773 k and moo2 can be gradually carburized to molybdenum carbide above 813 k. the molybdenum carbide formed from the carburization of moo2 with n-c4h10 below 893 k is alpha-moc1-x with fcc-structure, while hcp-molybdenum carbide formed above 933 k. during the evolution of moo3 to moo2 (>773 k) or the carburization of moo2 to molybdenum carbide (>813 k), deep oxidation, cracking and coke deposition are serious, in particular at higher reaction temperatures, these lead to the poor selectivity to aromatics. aromatization of n-c4h10 can proceed catalytically on both mo2c/hzsm-5 and moo2/hzsm-5, the distribution of the products for the two catalysts is similar below 813 k, but the, activity for mo2c/hzsm-5 is much higher than that for moo2/hzsm-5.
